本研究是以掀蓋式行動電話鉸鏈結構設計為實例，模擬與分析掀蓋式行動電話鉸鏈傳動機構及扭力值。 本研究以掀蓋式行動電話鉸鏈結構，利用座標系之定義、座標系之設定及座標轉換，設定傳動機構之座標系了解各元件在不同的座標系統之下其運動情形、運動特性等等的關係，推演出傳動機構之力學分析；針對凸輪輪廓曲面變化設計、壓力角及能量守恆原理，驗證模擬凸輪輪廓與真實凸輪輪廓之凸輪輪廓曲面與扭力值角度是具有參考的價值；使用有限元素分析軟體，模擬行動電話或電子器物結構分析，找出最大應力位置，進行變更設計結構造型，以補強結構本體。本文用一實際的掀蓋式行動電話鉸鏈實際實驗的量測扭力值，以本文理論模式扭力值及角度作比較，驗證本文理論模式是可接受，進ㄧ步利用實例將其所需的輸出角度與升程高度設定，合成所需的運動曲線；並舉實例說明輪廓曲面變化設計與扭力值的關係，並探討設計與製造結合理論與分析。 分析結果可進ㄧ步了解，掀蓋式行動電話鉸鏈結構之扭力值角度誤差主要受到凸輪幾何外型的影響；造成模擬凸輪輪廓與真實凸輪輪廓之誤差的原因，除了幾何外型，還包含真實實驗中嚙合誤差、製造過程的誤差。本研究成果將有助於了解掀蓋式行動電話鉸鏈結構模式及分析，為掀蓋式行動電話鉸鏈結構提供一個新的方向。
[ 英文摘要 ]
This article takes the Folder Type Mobile Phone Hinge design as an example for a study of simulation and analyzes the Hinge drive mechanism movement and the torque value. This article takes kinds of methods to get better understand the relationship of Hinge movement conditions and movement properties, such as definitions, settings, and conversions to the coordinate systems. Respecting to the CAM curvature design, pressure angle and energy conservation principle that we can get a creditable torque value and it’s related torque angle data by using a simulated CAM curvature analysis. Reinforce or redesign the Hinge structure after find out the maximum stress point on the simulated Mobile Phone or Electronic device through Finite Element Analysis software. Furthermore, the output angle and the acceleration height setting required by the practical example herein are taken to synthesized the required movement curve, and practical examples are submitted herein to demonstrate the relationship between designed CAM curvature surface, and the designed CAM torque value, the data can be the basic information for the further investigation to the integration of the design and manufacturing fields together with both theories and analysis. Based on the analytical results, it can be further understand that the deviation of torque value angle of Folder Type Mobile Phone Hinge structure is mainly affected by the geometric outline of the CAM design. Apart from CAM outline, the reasons for causing the deviation occurred between the simulated and practical CAM outline are the matching errors in the practical experiment and the deviations on the production process. The result of this study will do the helps for better understand the structure and the analytical model for Folder Type Mobile Phone Hinge, and providing a new direction of Folder Type Mobile Phone Hinge structure development.
